The company is betting big on nuclear energy to meet increasing power needs of data centers and new technologies like AI. Also, new research into a strange fish known as the sea robin finds that leg-like appendages can “taste” prey buried in the sand.

Three Mile Island in Pennsylvania has quite a reputation in the world of nuclear energy: One of its reactors suffered a catastrophic partial meltdown in 1979, earning the title of the largest nuclear accident in US history. The failed reactor has been inoperable since the accident, while the other reactor shuttered in 2019.

But now, tech giant Microsoft has made a deal with the nuclear site to reopen Three Mile Island, and purchase all of its generating capacity over the next 20 years. As Big Tech bets big on artificial intelligence, the need for electricity to power data centers is increasing tremendously. Former Microsoft CEO Bill Gates is a large investor in nuclear energy.

To help Science Friday celebrate Climate Week NYC, Casey Crownhart, climate reporter for MIT Technology Review joins guest host Anna Rothschild to discuss this and other top climate stories of the week.

Your legs may help you get around, but what if they could also help you sniff out a snack? That’s a trick achieved by a fish called the sea robin. The fish, which lives on the seafloor, has an unusual appearance, with wing-like fins and leg-like appendages that it uses to walk along the ocean bottom. But in work published this week in the journal Current Biology, researchers report that those legs are also chemical sensing organs that can taste for prey buried under the sand.

Dr. Nicholas Bellono, a professor of molecular and cellular biology at Harvard, first learned of the unusual fish on a visit to the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, where he was planning to obtain squid and octopus for another research project. MBL workers showed Bellono and colleagues the sea robin, and explained that they have a reputation for being able to locate hidden prey—to the point that other organisms will follow the sea robin, hoping to get in on the meal. The intrigued researchers brought some sea robins back to the lab, and began a series of experiments to better understand their prey-sniffing abilities.

Bellono joins guest host Anna Rothschild to talk about the fish, the genetic adaptations that allow it to sense the world through its legs, and the value of serendipity and curiosity-driven research in the scientific world.
